Loss of electricity and water for long periods

Loss of communications

Extensive road closures through flooding

Airport and shipping port closures

Vegetation damage

The cyclone warning system

The Bureau of Meteorology and the State Emergency Service (SES) will issue various warnings through the media during a cyclone.

‘Cyclone Watch’ announcements will be issued through radio and television by the Bureau of Meteorology when there is a risk that a cyclone will produce gale force winds within 48 hours (but not within 24 hours).

‘Cyclone Warning’ announcements will be issued through radio and television by the Bureau of Meteorology when gale force winds are possible in less than 24 hours. The announcements will rate the severity of a cyclone from Category One (weakest) to Category Five (strongest).

FESA SES will issue Community Alerts during the Cyclone Warning period.

Community Alerts advise of appropriate actions to be taken by the public as the cyclone come closer.

The alert stages are divided into BLUE, YELLOW, RED and ALL CLEAR WITH CAUTION as indicated in this pamphlet.

Alerts are issued through radio and television and are displayed in communities using coloured lights or flags.

Community Alerts may not be issued for Category One cyclones in some areas of the State.

Safety Tips

It may be necessary to evacuate some areas, such as storm surge threatened areas, before the cyclone arrives. If advised to evacuate, follow directions from Emergency Services; lock your house; switch off electricity, gas and water. Take a torch, sleeping bag, important documents and any necessary medications with you.

Wear long sleeved shirts, long pants and sturdy footwear so you can be protected as much as possible.

If staying in your home, move to the strongest part of the house.

If the house starts to break up, protect yourself with mattresses or get under a strong table or bed.

It is essential to turn off all power and light switches during a power cut to enable electricity authorities to re-establish power supplies efficiently and give added protection to your house in the event of damage.

Disconnect gas to avoid gas leakage should your pipes be damaged during a cyclone.

Do not stand near or open any windows or doors during the cyclone.
